Well all us Disney Princess fan poppers know that Moana is expected to join the girls in 2018 . But on November 23, 2016, a movie called Giants will come out. It is based on Jack and The Beanstalk. The main character will be Jack and his love interest will be Angelina. Angelina is
a rich girl and Jack loves her, however a boy named Marco also loves her. There is a love triangle. Angelina is expected to join the Disney Princess lineup in 2017 after the movie comes out.
I don't know if any of this information is completely sure to happen but if it is, I am glad Disney is waiting 2 years to make new princesses because I think that for now, 13 is enough.
